Final answer:
Meiosis occurs to ensure the right number of chromosomes end up in each pair. It is a specialized cell division process that produces haploid cells. There are two rounds of nuclear division in meiosis, resulting in four daughter cells with half the number of chromosomes as the parent cell.
Step-by-step explanation:
Meiosis occurs to make sure the right number of chromosomes end up in each pair. Meiosis is a specialized cell division process that produces haploid cells, which have half the number of chromosomes as the parent cell. During meiosis, there are two rounds of nuclear division resulting in four nuclei and usually four daughter cells, each with half the number of chromosomes as the parent cell. This ensures that the correct number of chromosomes end up in each pair.
